software regulating meter

◆The electric meter constant (HFConstant) is adjustable

◆Provide gain and phase correction

◆Provide active offset correction

◆Provide small signal calibration acceleration function

◆Provide automatic verification function for configuration parameters

◆Provide SPI/UART interface

◆Equipped with power monitoring function

◆Powered by a single+5V power supply, the typical power consumption is 14mW

◆Built in 2.5V ± 1% reference voltage, typical temperature coefficient of 5ppm/℃

◆Adopting SOP24 green packaging, compatible with RN8209G pins, without zero line ADC input and related measurement functions;

RN8207G is capable of measuring active power, active electrical energy, effective voltage, effective current, and voltage line frequency.

RN8207G supports all digital gain, phase, and offset correction. The active power pulse is output from the PF pin.

RN8207G provides SPI/UART interfaces for convenient communication with external MCUs.

The internal power monitoring circuit of RN8207G can ensure the reliable operation of the chip during power on and off.
